thank you very much ,I have a bit confused regarding swap file

i will be more clear.
if I have 4 page memory ,and it was empty at first. there are references from cpu :
3, 2, 1, 5, 3, 6, 2, 1, 7, 4, 6, 2, 4
can I consider 3,2,1,5 the first four references are pages fault or not? this is my question specifically
